*rom the foregoing it is to'be understood prevent the loadingfstrains at the head fillet 12- of the rail being focused onthe insulating material. To I avoid that and to-distribute the loadingstrains over 1 e5 that the present. invention is intended to flange portion 18 fitting the web of the rail 7 and thehead fillet 12 thereof and provided at the top with a thickened substantially triangular head member 19 approximately fitting the vacated area ,16 of the rail head; i

and seated against the inclined faces 15 of the rail head. The said head member'of the shoe 17 isformed at its underside with an inclined widened bearing surface '20 against whiz-3h bears the head piece of insulating material 21 held in operative relation tothe -j'ointstructure by the joint bar B and-the head 13- 14 thereof. Thebase part 'ofthi's form of the invention maybe insulated 'in any jconventional manner as for in'st'ance by the base piece 22' of insulation fitting the rail flange and the base part of the joint bar'which'for'illustrative purposes is shown as being ofthe continuous type of rail joint bar, though it will be understood that the present invention is not limited to any particular type of joint bar except that such. barmust have its head portion take a load- 'in'g engagement at the'head fillet of the rail and beneath the head part of the suppleir'nent'a'ry bearing unit 17 r Byway of illustrating the Wide range of -Inodi'fication to which the invention is'suscep- -tib1e there is shown in Fig; 2 of the drawings a modified form of supplementary'b'ean ing unit 17 with "merely a head enlargement 93 which has a pressing engagement against the inclined side 15 of the rail fhead andis formed at its underside as at 24: with the 'wld'ened bearing surface'for the head piece bf'insulation, in the same 'r'nannerand for the same purpose as shown in Fig; drawings.

formed of a heav fishing of the rail andprovided. W th a head-member BO extending outward from combinationfthe headfre'e type rail having' sloping bottom corners forming seat the joint bar, and a metal supplementary bear while not pressed against the inclined seat- 7 15 nevertheless provides the widened extended bearing for the head piece of insulating material.

As further illustrative of the invention reference is made to Fig. 5 of thexdrawings showing asuppIement'ary bearing unit '29 metal shim fitting the and beyond the head fillet of the. rail and formed at its underside with a widened supplementary bearing surface 31 for the head piece Ql Of insulation held in place by the joint bar B.
